FLY- ESCAPE.

Specification of Letters Patent.

Patented Dec. 21, 1920.

Application filed April 1, 1920. Serial No. 370,502.

To all whom it may concern 5e it known that I, CHARLES Ln RoY CAssADY, a citizen of the United States, and a resident of Marion in the county of Crittenden and State of Kentucky, have in vented certain new and useful Improvements in Fly-Escapes, of which the following is a specification.

My invention is an improyement in fly escapes, and has for its object to provide an escape of the character specified adapted to be used in connection with screens, for permitting flies to escape at the top of the screen, wherein the escape is formed from sheet metal cut or stamped and bent to shape, and capable of being easily attached to the screen frame at the top thereof.

In the drawings:

Figure l is a perspective view of the upper end of a screen provided with the improved escape;

Fig. 2 is a plan View of the blank from which the escape is formed;

Fig. 3 is a vertical section through the top of the screen frame;

Fig. 4 is a perspective view of the escape detached.

The present embodiment of the invention is shown in connection with a screen of usual form, comprising, a substantially rectangular frame 1 and a filling 2 of perforate material, as, for instance, wire cloth, which is secured to the frame in any suitable or desired manner. At the top of the screen frame and on the under side of the top cross member of the frame, at approximately the center thereof, the escape is secured.

This escape is formed from sheet metal, cut or stamped to shape, and consists of portions 3 and 4 which extend at approximately a right angle with respect to each other. At the junction of the portions 3 and 4 the plate is slitted longitudinally, as shown at 5, the said slit extending from near one end of the plate to near the other and at the ends of the slit the portion 4 has angular slits 6 extending from the slit 5. That portion 7 of the material between the slits is bent outwardly at a right angle to the portion 4, as clearly shown in Fig. 4. Preferably, the blank is provided at each end with a longitudinally extending lug 8 of triangular shape, the said lug having its base connected with the sheet, and having that side which is perpendicular to the base in line with the slit 5, and when the portions 3 and 4 are bent at a right angle with respect to each other, these lugs 8 are bent at a right angle to the said portions 3 and 4 and between'the said portions, acting as a brace for the portions.

The improved escape is secured to the window in the manner shown in Figs. 1 and 3, suitable securing means being passed through the portion 3 to connect openings through which may be passed nails or screws, to connect the said portion 3 to the under edge of the top cross member of the frame 1. A portion of the filling 2 of perforate material is cut away from the edge of the frame to the level of the portion or shelf 7, and this portion or shelf 7 extends through the cut away portion of the filling.

With the escape, when flies alight on the screen and move upwardly, which they do, they will eventually reach the opening formed by the out bending of the portion or shelf 7 and will escape through this opening to the outer air.

The device is inexpensive, easily applied and may be marketed separately from the screen, to be attached to existing screens.

Since the device is composed of thin sheet metal, it may be connected by tacks, which may be driven through the portion 3 in the material of the screen frame.

I claim:

A device of the character specified, adapted for connection with the top cross mem ber of a screen intermediate the ends thereof, and consisting of an angle plate com posed of two portions extending at approximately a right angle, one of the said portions being adapted to abut the cross member and the other to extend parallel with the screen, said last named portion having a part thereof separated at the junction of the two portions and bent outwardly to form an opening in the upper part of the said portion, and a substantially horizontal shelf below the opening, the said last named portion having at each end and in line with the opening, outwardly bent lugs.

CHARLES LE ROY CASSADY.
